SIM-NIN: How to unblock your line on any network

Nigerians have stormed telecommunication stores nationwide after telcos began barring following lines not linked with a National Identification Number (NIN) over the weekend.

This is in compliance with the Nigerian Communications Commission’s July 31, 2024, deadline for SIM-NIN linkage. According to the Association of Licensed Telecommunication Operators of Nigeria (ALTON), the umbrella body for all telcos, customers who have had their lines blocked are those with a mismatch between their records on both databases (i.e., SIM and NIN).

“We advise such customers to contact their service providers through communicated channels for resolution of the issue,” it said in a statement released on Monday.

It noted that all operators have put measures in place to ensure that anyone whose line is blocked can unblock it by following some easy steps:

1. Airtel: Dial *121# and input your eleven-digit NIN number. The subscriber will receive a confirmation message they have successfully unbarred their Airtel SIM card.

2. EMTS: 9Mobile: Dial *200*8#

3. Glo: Dial *109*Your NIN number#. For example, if your NIN is 12345678901, you would dial *109*12345678901#. Then follow the prompts to submit your NIN for linkage.

4. MTN: If an MTN line is barred, all the subscriber needs to do is visit nin.mtn.ng to check the NIN status, and if not linked, proceed to link it. During the process, an OTP would be requested, as well as the NIN. After giving consent and submitting the NIN linking request, it will be done, and the line will be automatically unbarred.
